Neighbor discovery method and device for unmanned aerial vehicle ad hoc network and unmanned aerial vehicle

Abstract

The invention provides a neighbor discovery method and device for an unmanned aerial vehicle ad hoc network and an unmanned aerial vehicle, and the method comprises the steps: periodically sending a beacon frame to each member node in each sending sector, so as to establish bidirectional alignment with each member node in the sending sector until bidirectional alignment with all member nodes is established; broadcasting the HELLO packet to the member node, so that the member node responds based on the HELLO packet to generate a REPLY packet; and generating a neighbor list based on the REPLY packet fed back by each member node. According to the neighbor discovery method and device for the unmanned aerial vehicle ad hoc network and the unmanned aerial vehicle provided by the invention, all member nodes can be distributed uniformly by the cluster head node after being aligned to the cluster head node in a scene with a relatively long communication distance and a relatively large network coverage area, and feedback information of the plurality of member nodes is received in sequence, so that compared with the traditional sequential traversal, the neighbor discovery efficiency is improved. The neighbor discovery speed and efficiency can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a neighbor discovery method and device for an ad hoc network of unmanned aerial vehicles, and an unmanned aerial vehicle. Background technique [0002] In recent years, with the rapid development of technologies such as artificial intelligence and the Internet of Things, UAV technology has entered a period of rapid development, with more and more types, and the scope of application has further expanded from the military field to urban anti-terrorism, disaster rescue and other application fields. . Due to the weak computing power of a single UAV platform, the task load it can carry is relatively single, so the ability to perform tasks is limited. By carrying different mission loads of multiple UAVs to carry out coordinated actions, and using wireless communication networks to achieve information sharing and capability complementarity, the ability to perform missions can be...
